BACKGROUND OF THE INVENTION
[0001] The present invention is generally directed to a dispenser product lockout system
and, more particularly, to a rolled web material dispenser having a mechanical lockout
feature that prevents use of a dispenser assembly for dispensing rolled web material
that is acquired from non-approved or unauthorized sources.
[0002] Conventional rolled web material dispensers for use in dispensing hand towel and
toilet tissue material or the like often advance the web material from a roll as the
roll rotates about a spindle, bobbin, or hub located within the dispenser. Upon depletion
of the rolled web material, the dispenser housing is opened, and a replacement roll
of web material is then placed within the dispenser. Conventional rolls of web materials
may be coreless or include a hollow core for receiving a generic or common spindle
that extends laterally through the core and whose opposing ends are supported by the
dispenser housing. When provided in a coreless configuration, the axially opposing
end located portions of the web material may be pinched between opposing fingers or
compression assemblies that collectively define the rotational axis of the roll of
web material relative to the dispenser.
[0003] Whether provided in a cored or coreless configuration of rolled web material, conventional
paper and web material roll dispensers are not commonly configured to selectively
dispense only a particular type, style, or roll of web material or a roll of web material
from a particular manufacturer. Accordingly, it is possible for a size discrepancy
or mismatch to occur between the dispenser and the roll of web material, thereby inhibiting
the proper dispensing of the web material.
[0004] Such systems also present the potential that service providers or employees may configure
such dispensers to dispense product having less desirable construction or performance
characteristics via cheaper source suppliers or the like. Shortcomings in the dispense
operation can sometimes be incorrectly attributed to subpar operability of the dispenser
assembly rather than being attributable to deviations in the manufacture of the discrete
rolled web material and/or use of rolled web materials that are ill-suited for being
dispensed from a given dispenser assembly or produced with subpar manufacturing practices.
Improper or less than efficient operation of the rolled web material dispenser to
dispense rolled web material in a repeatable manner, but attributable to improper
loading or use of a dispenser with web material not properly configured for cooperation
with a discrete dispenser assembly, may reflect adversely on the manufacturer of the
dispenser rather the establishment or service provider associated with maintaining
operation of the discrete dispenser assemblies once deployed and ensuring that only
suitable rolled web materials are associated therewith. Accordingly, there is a need
for a roll dispenser that is constructed to limit use of the dispenser assembly to
dispense only desired rolled web materials and thereby inhibit use of the dispenser
assembly to dispense rolls of web material that have not be authorized to be dispensed
from the corresponding dispenser.
[0005] Further, a need exists for lockout features that prevent necessary positioning or
support of unauthorized rolls of web material relative to a given dispenser. In such
a lockout system, in the event that there is an inconsistency between a registration
component associated with a core of the roll and a mating registration portion associated
with the hub or spindle of the dispenser, the roll of material will not be accepted
into the dispenser in an operable manner thereby inhibiting use and/or proper support
for dispensing of an unauthorized roll of web material.
[0006] A further need exists for a lockout roll dispensing system that is relatively inexpensive
to manufacturer, produce, and maintain in a useable condition, inhibits use of unauthorized
rolls of web materials, and solves other problems associated with existing configurations.
A still further need exists for a dispenser assembly roll of web material lockout
system that can be quickly and conveniently implemented into existing or previously
deployed dispenser assemblies and which includes separable elements that can be configured
to designate rolls of web material as authorized to be dispensed with dispenser assemblies
that have been reconfigured to include the lockout system. A need further exists for
roll web material lockout systems that provide robust support of authorized materials
to facilitate the sequential rotational dispensing of the web material from the bulk
roll. A further need exists for rendering a dispenser assembly incapable of supporting
those rolled web material rolls that do not include the mating registration element.
SUMMARY OF THE INVENTION
[0007] The present invention discloses a roll of web material lockout system that resolves
one or more of the shortcomings disclosed above.
[0008] One aspect of the present application discloses a web material roll lockout assembly
that includes a hub that is constructed to be supported by a dispenser. A channel
is formed in a radially outward oriented surface of the hub and positioned such that
the channel is formed proximate an end of the hub. The assembly includes an insert
that is constructed to removeably cooperate with the hub and has an overlapping portion
formed between opposing ends of the insert. A plurality of projections are defined
by the insert and constructed to limit axial translation between the insert and the
hub when at least one of the plurality of projections is engaged with the channel
and such that the overlapping portion of the insert improves flexibility associated
with movement of the plurality of projections. A first rotational bearing surface
and a second rotational bearing surface are defined between the insert and the hub
when the at least one of the plurality of projections is engaged with the channel.
The first rotational bearing surface and the second rotational bearing surface are
positioned so that the overlapping portion of the insert is disposed therebetween.
[0009] Another aspect of the present application discloses a method of restricting rolls
of web material that can be dispensed from a roll dispenser. The method includes providing
a hub that defines an axis of rotation of a roll of web material associated with the
roll dispenser. An insert is provided that has an outer diameter that is constructed
to securely engage a bore of a roll of web material and has a radially inward directed
shape that slideably cooperates with the hub. A portion of the insert is formed to
overlap itself as the insert traverses from opposing ends thereof and such that, when
the insert is engaged with the hub, cooperation of the insert and the hub restricts
axial translation between the hub and the insert and accommodates rotation of the
insert relative to the hub during rotation of a roll of web material. Engagement of
a respective insert with the hub defines at least two bearing surfaces between the
insert and the hub wherein each of the at least two bearing surfaces are offset in
an axial direction from respective longitudinal ends of the insert and the hub and
such that the overlapping portion of the insert is preferably disposed between the
at least two bearing surfaces.
[0010] A further aspect of the present application discloses an insert for use in a roll
web material dispenser assembly. The insert includes a body that extends between a
first end and a second end of the insert. An outer surface of the body of the insert
is shaped to be received in a roll of web material and an inner surface of the body
of the insert is shaped to removeably cooperate with a hub associated with a dispenser
and to define at least two bearing surfaces that are axially offset from one another
when engaged with the hub. The insert includes a plurality of deflectable fingers
that are associated with a first end of the body and a projection is associated with
at least one of the plurality of deflectable fingers and oriented to engage a groove
defined by the hub. The body defines an overlapping portion of the insert between
the first end and the second end of the insert and is positioned between the at least
two bearing surfaces.
[0011] Another aspect of the present application discloses a web material roll lockout assembly
that include a support arm that is constructed to engage a dispenser housing. A carriage
is engaged with the support arm and a hub is supported by the carriage such that the
hub is movable relative to the carriage between an exposed position wherein a portion
of the hub is accessible and a retracted position wherein the portion of the hub is
inaccessible. The assembly includes a biasing device that is configured to bias the
hub toward the exposed position. An insert is constructed to be disposed in a bore
of a roll of web material and to slideably cooperate with the hub so that the hub
engages the insert without translating the hub relative to the carriage toward the
retracted position.
[0012] A further aspect of the present application discloses a method of forming a web material
lockout assembly. The method includes forming an insert so that an outer geometric
shape of the insert allows the insert to be slideably received in a bore of a roll
of web material and forming an inner geometric shape of the insert to be shaped to
removeably cooperate with a hub supported by a dispenser. The hub is supported so
that the hub is slideable relative to the dispenser so that the hub is rendered inaccessible
for supporting engagement if an insert having a different inner geometric shape is
attempted to be operatively associated therewith.
[0013] Another aspect of the present application discloses a web material dispenser lockout
system that includes a support assembly that is constructed to cooperate with a dispenser
housing. A hub slideably engages the support assembly so that the hub is movable between
an extended position and a retracted position. A biasing device is engaged with the
hub and oriented to bias the hub toward the extended position. The lockout system
includes an insert that is constructed to be disposed in a bore of a roll of web material
and has a radially interior facing geometry that allows the insert to cooperate with
the hub without translating the hub toward the retracted position.
[0014] These and other aspects, features, and advantages of the present invention will become
apparent from the detailed description, claims, and accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] In describing the preferred embodiments of the invention which are illustrated in
the drawings, specific terminology will be resorted to for the sake of clarity. However,
it is not intended that the invention be limited to the specific terms so selected
and it is to be understood that each specific term includes all technical equivalents
which operate in a similar manner to accomplish a similar purpose. The various features
and advantageous details of the subject matter disclosed herein are explained more
fully with reference to the non-limiting embodiments described in detail in the following
description.
[0017] Illustrative embodiments of rolled web material lockout systems in accordance with
various aspects of the present invention are shown in Figs. 1 through Fig. 9. Figs.
1-5, and initially Fig. 1, shows a rolled material lockout system or lockout assembly
500 according to one embodiment of the present application and that is constructed
to cooperate with rolled web material dispensers or dispenser assemblies, such as
dispenser assembly 28, as shown in Fig. 1. Referring to Figs. 1 and 2, roll lockout
system 500 includes a hub 502 that is constructed to cooperate with support arm 22
associated with dispenser assembly 28 and an insert or core insert 504 that is constructed
to be received in a cavity or bore 210 of a roll of web material 172 and removeably
cooperate with hub 502. It is appreciated that support arm 22 may be constructed to
snap-fittingly cooperate with an enclosure or housing 202 defined by dispenser assembly
28 such that the roll material housed thereby can be dispensed in an unwinding or
unrolling manner when the housing 202 is oriented in a generally closed configuration
as disclosed further below.
[0018] Although being shown as removeably cooperating with support arm 22, it is appreciated
that hub 502 could be constructed in a generally unitary construction to include the
structure of support arm 22 associated with facilitating the connection of support
arm 22 to housing 202 of dispenser assembly 28. Roll support arm 22 is preferably
configured to snap-fittingly cooperate with housing 202 such that the support arm
22 extends in a generally linear manner along a length from a first end 30 to an opposing
second end 32. The first end 30 of the roll support arms 20, 22 preferably includes
one or more resilient catches which each preferably include a respective opposing
barb 38 formed proximate thereto and that are configured to releasably engage a receiving
slot formed in the dispenser housing 202. The opposing second end 32 of the roll support
arm 22 has a generally arcuate tab 40 that is configured to allow a user to selectively
deflect the respective support arm 22 in a generally outward lateral direction relative
to a roll of web material 172 to assist in the association of an authorized roll with
dispenser assembly 28 and/or the removal of the core of a spent or partially consumed
roll therefrom. It is further appreciated that opposing second end 32 of support arm
22 could be configured to cooperate with an interior facing surface of a cover 204
of dispenser assembly 28 when the cover 204 is oriented in a closed position. Such
a consideration allows the weight of the rolled web material to be distributed over
both ends 30, 32 of each respective roll support arm 22 and maintain a bias of one
or more of ends 32 in a direction toward engagement with roll of web material 172
when housing 202 is oriented in a closed orientation. Support arms 20, 22 are constructed
to support the opposing ends 212, 214 of a discrete roll of web material 172 in a
cantilevered fashion relative to the respective ends 30 of support arms 20, 22 and
the housing 202 of dispenser assembly 28 as disclosed further below.
[0019] When provided in a removable or selectively severable methodology, at least one of
arms 20, 22 defines a hub receiving area 42 that is disposed along a front or roll
facing surface of the length of the respective roll support arm 20, 22 between the
first and second ends 30, 32. Preferably, the hub receiving area 42 includes an optional
and preferably circular hollow center or void formed thereat. It should be understood
that the present invention is not so limited and that any alternative configuration
of the hub receiving area 42 is considered within the scope of the present invention.
Referring to Fig. 1, the hub receiving area 42 of one or more of support arms 20,
22 includes a plurality of receiving slots 36 that are annularly disposed proximate
the perimeter of the hub receiving area 42 for receiving and mating to the hub 502
as described further below.
[0020] During implementation, or upon depletion of the roll of web material 172, the cavity
190 of dispenser assembly 28 may be exposed to allow the user access thereto. Dispenser
assembly 28 includes a feed mechanism 192 that is constructed to cooperate with a
free end 195 of roll of web material 172 to effectuate each dispense activity. Feed
mechanism 192 includes a number of rollers 194, 196 that are constructed to effectuate
the dispense activity and thereby unwind the roll of web material 172 during each
dispense action. Dispenser assembly 28 includes an optional handle 198 that is operational
to effectuate manual operation of one or more of rollers 194, 196 to effectuate the
dispense activity. Although configured to accommodate manual dispensing operation,
it is appreciated that dispenser assembly 28 could be provided to operate in an automatic
or touchless manner via the inclusion of various proximity sensors and drive systems
configured to actuation operation of rollers 194, 196 in response to the proximity
of a user, or user's hand, relative to a throat or dispense opening 200 of dispenser
assembly 28 when in the ready for use configuration or with other manual actuation
assemblies such as manually operable lever arms, push paddles, or the like.
[0021] As disclosed above, housing 202 of dispenser assembly 28 is generally defined by
a cover 204 that movably or pivotably cooperates with a base 206 such that opening
of housing 202 of dispenser assembly 28 exposes cavity 190 associated with accepting
an authorized roll of web material 172. As shown in Fig. 1, dispenser assembly 28
preferably includes at least two support arms 20, 22 that are disposed on generally
opposite lateral sides of cavity 190. One of support arms 20, 22 includes a bobbin
or a boss 208 that is shaped to cooperate with a respective end of a bore or hollow
bore 210 of a roll of web material 172 of indiscriminate source. It is appreciated
that the axially extending bore 210 of the discrete rolls of web material can be defined
by a cigarette of the roll of material, a cardboard or other rigid material core tube
upon which the web paper material is wound, or other methodologies commonly employed
in the web paper roll material forming processes to create the hollow bore associated
with the roll of web material. Regardless of the methodology employed, boss 208 is
shaped to rotationally support a roll of web material from a majority of sources of
rolled web material. The other of support arms 20, 22 of dispenser assembly 28 is
provided with or otherwise constructed to define hub 502.
[0022] In the embodiment shown in Fig. 1, it can be appreciated that support arm 22 includes
the hub 502 of lockout system or assembly 500 as authorized roll of web material 172
includes a corresponding core insert 504 that is constructed to removeably cooperate
with or engage hub 502. It should be appreciated that the association of hub 502 and
insert 504 could be provided at either of the longitudinal ends 212, 214 defined by
roll of web material 172 or that dispenser assembly 28 can be readily configured to
operate with other lockout systems or assemblies, such as lockout assembly 600 as
disclosed further below, via the replacement of the respective lockout enabled support
arm 22 and/or engagement of other hubs 502 of hub assemblies 602 as disclosed further
below, associated with a discrete respective one of support arms 20, 22. It is further
appreciated that, although dispenser assembly 28 is shown as being equipped with one
lockout system or assembly 500, associated with accommodating use of dispenser assembly
28 with a roll of web material 172 having a corresponding respective insert 504 associated
with a respective one of lateral or axial ends 212, 214 of authorized roll of web
material 172, dispenser assembly 28 could be configured to include a pair of lockout
assemblies 500 wherein each lockout assembly 500 is associated with a respective one
of support arms 20, 22.
[0023] As mentioned above, it is appreciated that one of lockout assemblies 500, 600 can
be configured to cooperate with only one of the respective axial ends 212, 214 of
authorized rolls of web material 172 and in a manner wherein the "overhand" (as shown
in Fig. 1) or "underhand" unwinding orientation of the authorized roll of web material
172 relative to dispenser assembly 28 creates a desired presentation of the free end
195 of the authorized roll of web material 172 at feed mechanism 192 to effectuate
the desired continual sequential dispensing of the web material 172 from dispenser
assembly 28. After an authorized roll of web material 172 has been fully dispensed
or otherwise sufficiently depleted so as to merit replacement of a roll of web material,
housing 202 can be opened and the remaining disposable insert 504, absent its respective
supply of rolled web material 172, may be removed from the respective corresponding
hub 502 or hub assembly and subsequently discarded and/or recycled, and a new authorized
roll of web material 172 with a respective insert 504 orientation and construction
in accordance with the respective one or more of support arms 22, 122 to provide the
operative cooperation with the respective hub 502 or hub 602 can be associated with
underlying dispenser assembly 28 for continued use thereof. Whether provided with
one or more of, or mixed relations of, roll lockout systems 500, 600, dispenser assembly
28 can be expeditiously configured to allow operability of the dispenser assembly
28 to dispense only material from rolls of web material that have been previously
designated as acceptable for use with the respective dispenser assembly 28.
[0024] Figs. 2-5 show the hub 502 of roll lockout assembly or system 500 removed from dispenser
assembly 28 and insert 504 removed from the roll of web material 172. Referring to
Figs. 2 and 3 and as disclosed above, hub 502 of lockout system 500 is constructed
to removeably cooperate with insert 504. Hub 502 includes a dispenser facing side
506 having one or more projections 508, 510, 512 that are constructed to tool-lessly
and preferably snap-fittingly, wholly or partially rotatably, or otherwise selectively
removeably cooperate with at least one of roll support arms 20, 22 has disclosed above.
It is appreciated that the size and shape of that portion of hub 502 that is constructed
to engage the respective support arm could be provided in various sizes and shapes
and constructed to cooperate with support arms having various constructions.
[0025] Hub 502 includes an engagement interface 516 that is constructed to rotationally
support and axially cooperate with an engagement interface 518 associated with insert
504. Engagement interface 516 associated with hub 502 includes a first portion 520
that is generally defined by a post 522 that extends in an axial direction from a
barrel portion 524 of hub 502 along an axis of rotation about axis 526 associated
with the axis of rotation associated with a roll of web material 172 supported by
lockout system 500. Post 522 extends along axial direction of axis 526 between barrel
portion 524 and a distal end 528 defined by post 522. A channel 530 is formed proximate
the cantilevered free end or distal end 528 of post 522 and is constructed a snap-fittingly
cooperate with engagement interface 518 defined by insert 504 as disclosed further
below.
[0026] Barrel portion 524 of hub 502 includes an outer radial portion 527 that extends an
axial direction along axis 526 from the hub facing end of post 522. A shoulder 529
is defined by hub 502 and includes one or more ribs 525 that extend in axial direction
526 along the surface associated with radial portion 527 and cooperate with the radially
inward facing or directed surface of insert 504 when insert 504 is engaged with hub
502. Channel 530 formed in post 522 proximate distal end 528 is constructed to axially
cooperate with engagement interface 518 of insert 504 when insert 504 is engaged therewith
and oriented for dispensing operation. Insert 504 is defined by a body 538 that includes
an outwardly directed radial surface 536 that extends between the hub facing end 540
and an opposing or roll of web material facing end 544 of insert 504. One or more
optional projections 546 extend in a generally outward radial direction relative to
surface 536 of insert 504 and engage the radially inward facing surface of roll of
web material 172 to secure insert 504 relative to the bore defined by the respective
roll of web material, such as roll of web material 172, as disclosed above and as
shown in Fig. 1.
[0027] Referring to Figs. 2, 4, and 5, engagement interface 518 of insert 504 includes a
plurality of retainers or fingers 550 that extend from body 538 of insert 504 are
oriented in a cantilevered manner between respective discrete support ends 552 and
respective distal or free ends 554 associated therewith. That is, although each of
fingers 550 are defined by body 538 of insert 504, support ends 552 of fingers 550
are generally positionally associated with one another in a relatively continuous
manner whereas each of discrete free ends 554 are independently moveable in an at
least inward and outward radial directions relative one another. As disclosed further
below, fingers 550 and body 538 are preferably formed to allow a limited degree of
axial of axial displacement of free ends 554 relative to one another via an overlapping
portion of body 538 of insert 504 as disclosed further below.
[0028] A number of projections 560 extend in a generally inward radial direction toward
axis 526 from one or more of fingers 550 and preferably from each of fingers 550.
As shown in Figs. 4 and 5, insert 504 includes a radially inward directed cavity 562
that axially cooperates with a roll facing end portion 564 of hub 502 when hub 502
and insert 504 are engaged with one another. During axial translation of insert 504
toward hub 502, as indicated by arrow 570, distal end 528 of post 522 is shaped to
slideably, and preferably snap-fittingly, cooperate with a cavity 572 defined by the
circumference of fingers 550.
[0029] The slideable cooperation of post 522 with cavity 572 provides axial alignment of
hub 502 relative to insert 504 during placement of a roll associated therewith relative
to the underlying dispenser assembly 28. Continued axial translation of insert 504
relative to hub 502 in direction 570 allows distal end 528 of hub 502 to deflect discrete
retainers or fingers 550 in outward radial directions, indicated by arrow 576, until
discrete projections 560 associated with fingers 550 seat or otherwise slideably cooperate
with channel 530 defined by hub 502 such that insert 504 is axially positioned relative
to hub 502 and such that distal end 528 associated with post 522 is oriented laterally
outboard relative to insert 504. Although post 522 extends through insert 504, it
should be appreciated that the distal end 528 of post 522 is oriented in the bore
associated with the roll of web material 172 associated with insert 504. When insert
504 and hub 502 are engaged with one another such that projections 560 associated
with fingers 550 are engaged with channel 530 defined by hub 502, rotational interaction
of insert 504 and the roll of web material associated therewith relative to hub 502
is provided in a manner that allows the roll of web material to be rotated but with
limited free rotation therebetween after each dispense event. Such considerations
mitigate instances of dispensing more web material than is desired and/or free spinning
of the roll of web material 172 between dispense events.
[0030] Cooperation of one or more of projections 560 with cavity or channel 530 restricts
axial translation of insert 504 relative to hub 502 when a respective roll of web
material is associated therewith and without being acted upon by outside forces, such
as a user's removal of remainder of a mostly consumed roll of web material or a discrete
insert 504 associated with a recently consumed or fully dispensed roll of web material
172. As shown in Fig. 5, hub 502 and insert 504 cooperate with one another so as to
define a first bearing surface 580 and a second bearing surface 582 that are formed
between the respective adjacent radially facing surfaces of hub 502 and insert 504.
Bearing surface 580 of roll lockout system 500 is radially nearer axial centerline
526 than bearing surface 582. It should also be noted that in addition to the radial
spacing of bearing surfaces 580, 582, bearing surface 580 and bearing surface 582
are also offset relative to one another along axis 526. Such a construction provides
stable rotational support between insert 504, and a roll of web material associated
therewith, and the hub 502 associated with the respective underlying dispenser assembly
and/or respective support arm 22, 122 associated therewith and as disclosed further
above. Bearing surfaces 580, 582 further each provide a generally circumferential
rotationally supported interaction between hub 502 and insert 504 when associated
with one another and do so in a manner that offsets the rotational support between
hub 502 and insert 504 from the axial indexing cooperation associated with the cooperation
of projections 560 with channel 530. Such considerations provide robust rotational
support between hub 502 and insert 504 to better accommodate the mass of a full roll
of web material when associated therewith.
[0031] It is appreciated that the construction and orientation of the plurality of retainers
or fingers 550 associated with roll lockout system 500 can similarly be provided in
numerous configurations. As mentioned above, upon consumption of a discrete roll of
web material associated with dispenser assembly 28 and supported by lockout system
500, user manipulation of insert 504 allows fingers 550 to deflect in respective outward
radial directions, indicated by arrows 576, to facilitate the removal or disengagement
of a discrete insert 504 from the relative underlying hub 502 to accommodate replacement,
replenishment, or re-loading of dispenser assembly equipped with hub 502 with a roll
of web material having an insert 504 associated with its bore and thereby correlating
to an authorized respective roll of web material.
[0032] It is further appreciated that roll lockout system 500 can be configured with other
radially spaced and/or numbers of deflectable retainers or fingers and/or numbers
and constructions other than that which is shown in the drawings. For instance, it
is appreciated that fingers 550 may be provided in more of fewer fingers 550 than
shown in the figures, other radial shapes or sizes, and/or to have projections 560
associated therewith and/or configured to cooperate with a respective portion of insert
504 so as to facilitate the rotational cooperation therebetween, the axially indexed
relative position therebetween, and do so in a manner that mitigates axial dissociation
or translation of insert 504, and the roll of web material associated therewith, relative
to hub 502, during use of the underlying dispenser assembly. It is envisioned that
as few as two fingers 550 may be provided and may be provided to extend a similar
or dissimilar circumferential distance about channel 530 and be spaced about the circumference
thereof so as to maintain the desired rotational cooperation between hub 502 and a
respective insert 504 associated therewith and without negating the manually separable
cooperation of insert 504 with post 522 upon consumption or use of a discrete roll
of discrete web material. As disclosed further below, it is appreciated that, due
to the similarities in their size and constructions, insert 504 is preferably constructed
to interchangeably cooperate with hubs or hub assemblies having constructions that
differ from hub 502.
[0033] Referring to Figs. 2, 4, and 5, body 538 of insert 504 of roll lockout system 500
includes an overlapping portion 592 such that body 538 of insert 504 has a generally
S or Z shaped cross-sectional shape as the shape or cross-section of insert 504 progresses
between end 544 associated with fingers 550 and hub facing end 540 of body 538. Although
shown as being generally axially aligned with bearing surface 580 when insert 504
is engaged with hub 502, it is appreciated that overlapping portion 592 of insert
504 is may be disposed in alignment with bearing surface 582 or disposed between bearing
surfaces 580, 582. It should be further appreciated that overlapping portion 592 of
insert 504 is disposed between bearing surfaces 580, 582 in both the axial direction
associated with axis 526 and the radial direction as indicated by arrows 576. As shown,
the separation between adjacent fingers 550 extends between an open end proximate
projections 560 and a closed end proximate overlapping portion 592 such that each
finger 550 extends in a cantilevered manner relative to the remainder of body 538
from a position proximate overlapping portion 592.
[0034] Preferably overlapping portion 592 is formed toward the hub directed side of insert
504 relative to axis 526 and relative to end 544 thereof. That is to say, although
insert 504 could be constructed such that overlapping portion 592 be oriented axially
outboard of each of bearing surfaces 580, 582, overlapping portion 592 is preferably
shaped and positioned to be axially aligned or overlapping in radial directions one
of bearing surfaces 580, 582 or located axially therebetween. Regardless of the relative
location, overlapping portion 592 is constructed to maintain the deflectable nature
associated with operation of fingers 550 relative to hub 502, facilitate initial alignment
of an insert 504 equipped roll of web material with hub 502, attain the desired engagement
of a roll of web material with the dispenser, removal of any residual portion associated
with a previously consumed roll of web material, and do not otherwise interfere with
or detract from the dual bearing surface 580, 582 rotational support associated with
the rotational dispensing engagement provided by the selectively severable association
of discrete inserts 504 and hub 502.
[0035] Figs. 6-9 disclose a roll lockout system 600 according to yet another embodiment
of the application. Like lockout system 500 as disclosed above, lockout system 600
includes a hub 602 that is constructed to selectively cooperate with an insert such
as insert 504 in the manner disclosed above. As such, like reference numbers are used
hereafter with respect to the construction of insert 504. As disclosed above, insert
504 is constructed to cooperate with a bore 607 of a roll of web material 609 such
that, when disposed therein, insert 504 is preferably rendered non-removable from
roll of web material 609 save for the depletion thereof and/or destruction of any
residual portion of the respective roll of web material such that insert 504 can be
considered reusable, recyclable, and/or disposable.
[0036] Unlike the lockout system 500, hub 602 cooperates with a support arm or support arm
assembly such that hub 602 is rendered movable relative thereto. As shown, hub 602
cooperates with a support assembly that includes a support arm 606 and a carriage
608 that is engaged therewith. Support arm 606 is defined by a body 610 that is constructed
to engage a housing such as housing 202 (Fig. 1) in a manner according to one or more
of the methodologies disclosed above. Preferably, body 610 of support arm 606 is constructed
to snap-fittingly cooperate with the respecting housing such that a forward oriented
hub supporting portion of body 610 is offset from the interior facing surfaces of
the housing and such that roll of web material 609 can be supported by hub 602 when
hub 602 is engaged with support arm 606.
[0037] A passage 612 is formed through body 610 of support arm 606 and is shaped to cooperate
with respective portions of carriage 608 and hub 602 associated therewith as disclosed
further below. One or more openings 614, 616, 618, 620 are formed through body 610
of support arm 606 and are generally disposed about passage 612. One or more handles
or tabs 622, 624 extend in an outward radial direction from body 610 relative to passage
612. Tabs 622, 624 are generally accessible to the user to facilitate user interaction
with support arm 606 and a respective core or cigar associated with a sufficiently
depleted roll of web material 609 to assist with the selective separation between
hub 602, the core or any portion of a spent roll of web material 609, or an insert
504 that may be associated therewith during reloading of a dispenser assembly equipped
therewith.
[0038] Referring to Figs. 7 and 8, carriage 608 is defined by a body 630 having a roll or
insert facing surface or side 632 and a support arm facing surface or side 634. A
passage 636 and one or more openings 638, 640, 642 are formed through body 630 of
carriage 608. Openings 638, 640, 642 are generally disposed circumferentially about
passage 636 such that each of passage 636 and openings 638, 640, 642 are fluidly isolated
from one another and preferably circumferentially bounded by body 630 of carriage
608. As disclosed further below, such a construction maintains a relative rotational
orientation of hub 602 relative to carriage 608 when hub 602 is associated therewith
and in a manner that accommodates selective axial translation of hub 602 relative
to carriage 608 in the manner disclosed further below.
[0039] A wall 644 is generally formed about a perimeter of body 630 and includes one or
more projections 646, 648, 650, 652 that extend in an outward axial direction toward
support arm 606. A catch 654 is formed proximate the distal end of each projection
646, 648, 650, 652. Catches 654 and projections 646, 648, 650, 652 are constructed
and oriented to cooperate with respective openings 614, 616, 618, 620 defined by support
arm 606 such that carriage 608 snap fittingly cooperates therewith such that carriage
608 is positionally fixed relative to support arm 606 when engaged therewith. A plurality
of projections or arms 660, 662, 664, 666, 668, 670 extend in a rearward axial direction
relative to support arm facing side 634 of carriage 608 and are disposed radially
proximate openings 638, 640, 642 thereof. A barb 672 is formed near the free or distal
end 674 of one or more of arms 660, 662, 664, 666, 668, 670. Arms 660, 662, 664, 666,
668, 670 are radially spaced from one another and oriented so as to generally define
a hub cavity 678 therebetween. Arms 660, 662, 664, 666, 668, 670 are deflectable to
accommodate association or placement of hub 602 within hub cavity 678 and have an
at-rest orientation wherein barbs 672 overlap the radial footprint of hub 602 once
hub 602 is position therein. As should be appreciated from Fig. 8, hub 602 is insertable
into hub cavity 678 from a direction facing support arm 606 such that, once assembled,
removal of hub 602 from hub cavity 678 in a direction toward the roll cavity of the
dispenser cavity is prevented. As disclosed further below, hub cavity 678 is shaped
to support hub 602 such that hub 602 is axially moveable or slideable therein relative
to carriage 608.
[0040] Still referring to Figs. 7 and 8, hub 602 is defined by a body 680 having a post
682 and one or more projections 684, 686, 688 that are disposed circumferentially
thereabout. Body 680 of hub 602 defines a cavity 690 that is disposed between a portion
of post 682 and generally bounded by projections 684, 686, 688. Cavity 690 is shaped
to cooperate with a biasing device, such as a spring 692 or the like. When assembled,
opposing ends of spring 692 cooperate with carriage 608 and hub 602 to urge hub 602
and carriage 608 toward one another. When assembled, biasing device 692 biases hub
602 relative to carriage 608 and support arm 606 toward an orientation wherein post
682 of hub 602 passes through passage 636 of carriage 608 and extends axially beyond
roll facing surface 632 of carriage 608. When oriented in such a position, projections
684, 686, 688 of hub 602 pass through respective openings 638, 640, 642 defined by
body 630 of carriage 608 and similarly extend axially beyond roll facing surface 632
of carriage 608 such that post 682 and projections 684, 686, 688 are each available
for interaction with respective insert 504 and a roll of web material 609 associated
therewith. Such an orientation is shown in Fig. 6 wherein post 682 and projections
684, 686, 688 associated with hub 602 are oriented in an exposed or accessible orientation
696 available for interaction with insert 504 and a respective roll of web material
609 associated therewith.
[0041] Referring to Fig. 9, when oriented in the accessible orientation 696, post 682 defines
a first bearing surface or interface 700 associated with interaction with insert 504
and projections 684, 686, 688 define a second bearing surface or interface 702 associated
with engaging a respective insert 504 having a construction suitable to allow operative
rotational but axially fixed engagement therewith such that the projections 560 associated
with respective fingers 550 are engaged with a channel 704 defined by post 682. Overlapping
portion 592 of insert 504 rotationally cooperates with an exterior surface of post
682 and a radially outward directed surface of projections 684, 686, 688 rotationally
cooperates with a radially inward facing surface of insert 504. It is appreciated
that the relative position and construction of bearing surfaces 700, 702 and overlapping
portion 592 associated with the cooperation and engagement of insert 504 and hub 602
can be provided in any of the alternate relative constructions, relative to one another
and/or each other, disclosed above with respect to the cooperation of insert 504 with
hub 502. Regardless of the relative configuration therebetween, biasing device 692
provides sufficient force to tolerate the slideable association of insert 504 with
hub 602 such that projections 560 defined by insert 504 can achieve operative engagement
with channel 704 defined by hub 602 when an insert constructed for operative engagement
with hub 602 is associated therewith.
[0042] If however a user attempts to associate or otherwise engage a roll of web material
having an improperly configured insert with hub 602, such action translates hub 602
in an axial or lateral direction, indicated by arrow 708, relative to carriage 608
within hub cavity 678 such that post 682 and projections 684, 686, 688 will retract
through the respective passage and openings defined by carriage 608, and against the
bias of spring 692, such that hub 602 is rendered no longer available or exposed for
operative interaction with such an insert. Barbs 672 associated with arms 660, 662,
664, 666, 668, 670 mitigate undesired separation between hub 602 and carriage 608
during such instances and are oriented to interact with a stop 712 defined by body
680 of hub 602. Barbs 672 and stop 712 are configured and oriented to prevent continued
lateral displacement of hub 602 relative to carriage 608 and to maintain the desired
slideable association between post 682 and projections 684, 686, 688 of hub 602 with
passage 636 and openings 638, 640, 642 of carriage 608, respectively.
[0043] During dissociation of the conflicting insert from interaction with hub 602, biasing
device 692 acts to return hub 602 from retracted positions relative to carriage 608
toward the exposed, available, or accessible orientation or configuration 696 as the
conflicting insert is moved away from or otherwise dissociated from interaction with
hub 602. As such, when an appropriately configured insert 504 is associated with hub
602, the interface therebetween provides a configuration having multiple bearing supports
and a methodology that prevents use of dispenser assemblies equipped with hub 602
for use with rolls of web material having inserts that are improperly configured for
suitable rotational interaction with hub 602 by physical movement of hub 602 to positions
wherein the hub is rendered unavailable for operational interaction with such inserts.
[0044] Therefore, a web material roll lockout assembly according to one embodiment of the
present application discloses a hub that is constructed to be supported by a dispenser.
An insert is constructed to rotationally cooperate with the hub when the insert is
disposed in a bore of a roll of web material and the roll of web material is associated
with the dispenser. A channel is formed in a radially outward oriented surface of
the hub and positioned such that the channel is formed proximate an end of the hub.
The assembly includes an insert that is constructed to removeably cooperate with the
hub and has an overlapping portion formed between opposing ends of the insert. A plurality
of projections are defined by the insert and constructed to limit axial translation
between the insert and the hub when at least one of the plurality of projections is
engaged with the channel and such that the overlapping portion of the insert improves
flexibility associated with movement of the plurality of projections. A first rotational
bearing surface and a second rotational bearing surface are defined between the insert
and the hub when the at least one of the plurality of projections is engaged with
the channel. The first rotational bearing surface and the second rotational bearing
surface are positioned so that the overlapping portion of the insert is disposed therebetween.
[0045] Another embodiment of the present application discloses a method of restricting rolls
of web material that can be dispensed from a roll dispenser. The method includes providing
a hub that defines an axis of rotation of a roll of web material associated with the
roll dispenser. An insert is provided that has an outer diameter that is constructed
to securely engage a bore of a roll of web material and has a radially inward directed
shape that slideably cooperates with the hub. A portion of the insert is formed to
overlap itself as the insert traverses from opposing ends thereof and such that, when
the insert is engaged with the hub, cooperation of the insert and the hub restricts
axial translation between the hub and the insert and accommodates rotation of the
insert relative to the hub during rotation of a roll of web material. Engagement of
a respective insert with the hub defines at least two bearing surfaces between the
insert and the hub wherein each of the at least two bearing surfaces are offset in
an axial direction from respective longitudinal ends of the insert and the hub and
such that the overlapping portion of the insert is preferably disposed between the
at least two bearing surfaces.
[0046] A further embodiment of the present application discloses an insert for use in a
roll web material dispenser assembly. The insert includes a body that extends between
a first end and a second end of the insert. An outer surface of the body of the insert
is shaped to be received in a roll of web material and an inner surface of the body
of the insert is shaped to removeably cooperate with a hub associated with a dispenser
and to define at least two bearing surfaces that are axially offset from one another
when engaged with the hub. The insert includes a plurality of deflectable fingers
that are associated with a first end of the body and a projection is associated with
at least one of the plurality of deflectable fingers and oriented to engage a groove
defined by the hub. The body defines an overlapping portion of the insert between
the first end and the second end of the insert and is positioned between the at least
two bearing surfaces.
[0047] Another embodiment of the application discloses a web material roll lockout assembly
having a support arm that is constructed to engage a dispenser housing. A carriage
is engaged with the support arm and a hub is supported by the carriage and movable
relative to the carriage between an exposed position wherein a portion of the hub
is accessible and a retracted position wherein the portion of the hub is inaccessible.
A biasing device is configured to bias the hub toward the exposed position and an
insert is constructed to be disposed in a bore of a roll of web material and to slideably
cooperate with the hub so that the hub engages the insert without translating the
hub relative to the carriage to the retracted position.
[0048] A further embodiment of the present application discloses a method of forming a web
material lockout assembly. The method includes forming an insert so that an outer
geometric shape allows the insert to be slideably received in a bore of a roll of
web material and an inner geometric shape that is shaped to removeably cooperate with
a hub supported by a dispenser. The hub is supported so that the hub is slideable
relative to the dispenser so that the hub is unavailable for engagement if an insert
having a different inner geometric shape is attempted to be associated therewith.
[0049] A further embodiment of the present application discloses a web material dispenser
lockout system that includes a support assembly that is constructed to cooperate with
a dispenser housing. A hub slideably engages the support assembly so that the hub
is movable between an extended position and a retracted position. A biasing device
is engaged with the hub and oriented to bias the hub toward the extended position.
An insert is constructed to be disposed in a bore of a roll of web material and has
a radially interior facing geometry that allows the insert to cooperate with the hub
without translating the hub toward the retracted position.
